Task $4$: ASCII Arithmetic

Since ASCII characters are just numbers in a table, they can be represented in many different bases. For

example, the character $$e$$ can be represented as $65$ in hexadecimal representation and $01100101$ in binary.

Hence, by converting between hexadecimal and decimal, we can do arithmetic calculation using the ASCII

characters.

$1.$ Write the ASCII character which results from the following substractions from or additions to other

characters:

$($a$)$ A $+3=$

$($b$)$ z $7=$

$($c$)$ H $+8=$

$($d$)$ j $+2=$

$($e$)$ C $+9=$

$2.$ Write the integer that must be added or subtracted to satisfy the following conditions.

$($a$)$ What should be added to the ASCII code of $0$ to get the ASCII code of $9?$

$($b$)$ What should be subtracted from the ASCII code of $$c$$ to get $$G$$

$($c$)$ What should be added to ASCII code of $$E$$ to get $$k$?$

$($d$)$ What should be subtracted from the ASCII code of $$m$$ to get the ASCII code of $$S$?$

$($e$)$ What should be added to the ASCII code of $2$ to get the ASCII code of $8?$

$($f$)$ What should be multiplied by the ASCII code of $6$ to get the ASCII code of $$l$?$

$($g$)$ What should the ASCII code of $$x$$ be divided by to get the ASCII code of $(?$
